To all wao/1t fz @may concern: Y Y

Be it known that we, PETRUS MiiniiNUs Dine and MATiiiJs VAN DEN HnUvni.,subjects of the Queen ofV the Netherlands, residing at Uden, Province ofNoord Brabant, in the Kingdom of the Netherlands, have invented certainnew and useful improvenie-nts in Machinesl for Automatically BindingHead Ends of Straw Cases, of which the following is a specification.

The invention relates to a machine for automaticallj.v binding theheadends of strawcases, adapted to pack bottles and the like. riheinvention has for its object to bind these strawcases in Yquite a novelmanner. Binding the cases manuallyv whereby the cases, prior to thebinding, are conipiessed in a clamp, does not enable a high productionto be obtained andcauses high -production costs.

ln well-known machines thelieadends or" the cases are closed by formingaf stitching at the lieadends, or by wrapping metal-wire around saidends. Y

The machine according to the present invention, howeifer, is arranged insuch aVV manner that the binding-thread, approximatelf.v iii thedirection of the diameter of the cross-section of the head of the case,isV

pulled through the latter, then is wound one and a half times around thehead and then again is pulled through the head oit the case ,Y in thesame direction and finally is tensioned and cut oft'.

This inode ot' binding isisiinple, andA loosA ening ot the case-s boundin this manner is practically impossible. As the time required Y t'oi'machine binding the cases iii `this manner is very short, the output ofthe machine according to the invention is higher thanl hithertoattained. A

rEhe invention also relates to mechanism of such organization that thebinding-thread is drawn in one single movement successively through twosucceeding casesjafter which it is wrapped around the second of thesetwo cases and then is pulled throughV approximately in a straight lineandthen in acircle,and during the rectilinear move-Y ment the strawcasesare "moved inthe opposite direction over an equaldistanc'e. y

Y In order to obtain this result, the threadranged on a slide movableperpendicularly to the longitudinal axis Vof the threadguide in a-guideplate, which "derives a reciprocating motion at vthe same timefroni twoeccentrics, acting atan angle of lapproximately 900, the apparatusbeingvconstructed inv such a manner that, at the conclusion oi theperformance of six half strokes, the slide fails to participate duringVtwo half-strokesVV in the movement imparted tothe guideplate by oneofthe eccentrics. v

l The particular'inanner in V.which themaAY i chine `is constructedaii'darranged to cut oil' the binding wire at the proper point and inthe right manner will be Vfully described hereinafter with` reference to`4the accompanying drawings, as well as the particular shape which canbe given tothe threadV guide according to the invention.

In the accompanying drawings 60V guide, according to the invention, isar-f Figure l is a side elevation of a machine according to vtheinventioni Fig. :Zie a front elevation of the machine illustrated inFig. l'. Y

Figf is a side elevation on a larger scale, and n Fig. 4 a frontelevation of an .inferior part of thejmachine. Y

Figg shows.diagrammatically the manner in which the lieadends ofstrawcases are bound Vwith the machine according to the invention. .Y

Figs. V6 and 'r' are respectively a front andy side elevation of partsof thefmechanism on;` an enlarged scale,VVA Y Withreference to Fig.YV 5,it first: will be explained in what manner the heads'ofthe case'are'bound with the machine according to the invention. j

The binding thread l, comin i from the winding drum, is irstpulledtiliroughV the head of the case approximately in the 'direction ofthe diameter of the lcross-section of' the head, and then is woundaround'the. entire circumference of this head (portion b), whereafter itis woundfhali" a timeq around the case vv(portionVv c), soztha't VtheYbinding thread is again returned vto? the`v starting point yof the'wliole--oper'atioiif respect to the shaft. The slidevis pulled i downby the springV ell and rests with Ythe cam 42 of the leg Ll() on theguide pla-teer the guide piece 36 of the eccentric.

A second stop 43 of the slide 26 serves to prevent a periodical downwardmotion of this slide. For this purpose a hub with an arm 44 is keyed tothe shaft 6, said arm being provided with a curved sector. I The arm #leis of such length that a rotation ofthe shaft 6 causes the sector l5 toengage with 'the stop #t3 and prevents the slide 26 beingV lowered. Onlythe guide plate then follows the movement of the two eccentrics, and theslide does not participate in the movement caused by the eccentric 29,so that the thread guide y 23 at the lower end of the slide is no longermoved in the circumference of a circle, but approximatelyv horizontallyin a straight line. The shaft 6 is driven by the Avshaft 5 by means ofgear wheels 46 and 4T and a chain 4:8 at such speed, and the segment 4:5is of such diameter, that everytime after having circularly revolved oneand a half times, that is to say, after the guide plate and the slide 26have made siX half strokes,I the thread guide then hasr reached,(for'instance, the point f in Fig. 3), the slide 26 is held fast aboutthe middle of the downward lstroke by the sector, which at that momentengages the cam 43. The guide plate 25 then moves downwardly against thetension of the spring 4:1, over the last half stroke, then over a halfstroke upwardly, after which the member 36 strikes against the. cam

and the slide is again carried with the guide plate until after sixhalfstrokes (at which moment the guide plate and lthe Vslide are againmidway their downward movement), the segment 45 again engagingfthc cam43 and theslide and'held fast during two vertical half strokes of theguide plate.- The eccentric 37 on the shaft 30, however,

continuously acts on the guide plate and slide. Consequently, the threadguide moves along the dotted path (Fig.l 3), as follows The principle onwhich the invention isV based is not changed at all inthe event of thebinding thread being wound around the casehead two and a half, insteadof being wound one and a half times around the' said head. In using verysmooth strawcases or smooth binding threadv this might be nec-V essary,in order to obtain a very good'c'onnection. By suitable choice of therelation( of the speedlof the shafts 5 and 30 this can be attainedwithout any .further clrange.V The binding thread Vl carried through thecentral opening Vof the thread guide, 'there-v fore, is pulled througheach strawcase inl the manner indicated in Fig. 5. Y

AsY already explained above, the machine shown'net-only movesthethread-guide, but also the'cases themselves, and in "such *aiapproximately in a straightline over the distance, j', .uthe stra'wcasesareV moved in opposite directions, so that,v while the thread guidemoves from f'to 7L (Fig. 3)'th'e Vthread guide successively passesthrough two strawcases (for instance land H in lFig. 5), whereby thethread portion d is i passed"k through the case I' andthe thread portion@through vcase H. fInr the 'conf structionl shown the shaft .4e withythe guide .wheel l0-'and the drum 12 is driven insuch manner while thethread guide moves over the distance e', It 3), that the cases to bebound are moved opposite the thread guide. For this purpose aratchet-wheel a9y (F ig. 2) is secured to the shaft el, which ratchetwheel is moved by a rod 50 with yprovided with an automaticallykreciprocated tapering knife 54 arranged opposite the guide wheel 10 andpassing during its movement through the openingsV 53, therebyV carryingalong the binding thread l stretched in front of these'openings,'whereby in the two adjacent'cases the binding thread is again pulled, so thatthe heads ofV the vcases are boundv very tightly.l yAs thev edge of theknife'e is not veryV sharp the thread is cut only after it has beentightened sulliciently. The' dimensions of the open. ings l5,3 and ofthe tapering knife 54 can be so determined that after moving the saidknife a certa-in distanceto'tighten or stretch the binding thread, theVlattery .is clamped betweenthe edges of the` openings '53 and theknife, and by further-moving the knife the tension of thebinding threadis increased'to such'ra degree that the thread is .severedbythe knife.vVAsthe guide wheel tal shaftv 55 mounted-in V the frameV 3. The part 57of the knife holder, extended 'at the" l other Vvside of the pivot, isprovided at its end with a'plate 58` with which, during 'thev rotationof the shafty @engagesA a roller 59,

on the end of a crank pin 60, so that the said knife holder 56 isVreciprocated against the action of a spring 61 cooperating therewithand whereby the knife 54 is given the desired stroke.

in order to cut oftI the case heads 'at the required length prior to thebinding operation to obtain a. clean and smooth cut, the machine is alsoprovided with an automatic shearing device or knife 62 arranged at asuitable distance from and" parallel to the guide wheellO, said knife 62being movable vertically in a'xed guide plate 63 along a secondknifeGllf. rlhe shearing device is so arranged that the case-heads ofthe cases lying in the guide wheel 10 are cut ofi uniformly bythe saidknife 62 before they, attain the position opposite the thread guide Theup and down motion of the knife 62 is obtained by means of a rod 65, theupper end of which is connected to a crank 66 of the shaft 6.

On a lateral support G7 secured to the base 2 a spring actuatedsectional guide roller 68 is mounted and carried by a hinged lever 7 O,which is kept in the desired position byv a spring 69 associatedtherewith. The two halves of the roller 68 are pressed against eachother by a spring 7l'engaging the same, so that the binding thread isalways maintained sufiiciently tight.l
